1N4752ATR

Overview

The onsemi 1N4752ATR is a single-channel general-purpose Zener diode with a nominal voltage of 30 V and a maximum power dissipation of 1 W. It features a 5% tolerance, DO-41 through-hole package, and operates within a temperature range of -65°C to +200°C. The device has a test current of 8.4 mA, maximum Zener impedance of 35 Ω, and reverse leakage current of 5 μA.

Feature Summary

• Provides stable voltage regulation in the 30 V range for circuit protection and reference applications
• Utilizes a robust glass passivation process for enhanced reliability under thermal stress
• Designed for high-temperature operation up to 200°C junction temperature

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Procurement Notes

Verify the specific suffix 'ATR' corresponds to the reel packaging format required by your assembly line. Confirm that the 30 V nominal rating aligns with your design specifications. Ensure compatibility with standard DO-41 footprint dimensions during PCB layout. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or material declarations prior to final procurement approval.

Selection Notes

Select this component when a 30 V Zener voltage is required with 1 W power handling capability. The DO-41 package suits through-hole mounting processes. Consider the 5% tolerance for general regulation tasks where tight precision is not critical. Evaluate the operating temperature range to ensure suitability for high-thermal environments.

Part Context

This part belongs to the 1N47xxA series of 1 W Zener diodes manufactured by onsemi. The series offers a wide range of voltage options from low voltages up to higher thresholds, all sharing similar physical and electrical characteristics. The 1N4752ATR specifically targets the 30 V segment of this established product line.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4752A variants in DO-41 packages. Verify electrical equivalence regarding voltage tolerance and power dissipation before substitution.
